User buys ₦40,000 of goods from a merchant. Your BNPL product splits payment into four ₦10,000 installments: first one at checkout, three more every two weeks. You pay the merchant ₦39,000 upfront (you took a 2.5% fee). You collect ₦10,000 from the user now, then ₦10,000 every 14 days for the next 42 days. Your accounting needs to reflect: a receivable from the user that DECREASES with each installment, a payable to the merchant that goes to ZERO when you fund them, your gross revenue (the fee), AND your float exposure (the unpaid ₦30,000). This lesson walks the first three of the five events.
